From $699.99View productMark 7 owners
Running an Evolution, APEX 10, or Revolution with an Autodrive? Every RCM sensor is built to drop into Mark 7 station layouts with no machining, connect directly to the Autodrive, and stop the press the moment a charge, bullet, or case is out of spec. We're an independent Wyoming shop — not owned by, sponsored by, or affiliated with any press manufacturer — and we run Mark 7 machines in our own loading room every week.
Why upgrade
The factory PowderCheck probe reports pass/fail through over/under windows. RCM laser powder checks measure the actual powder level in every case — no probe contact, no spills, no probe swaps between cartridges — and hold much tighter windows without false-alarm fatigue. Pro models log every round with timestamps and CSV export, so a clean session is something you can prove, not assume. Already running the factory probe? Our centering dies for the Mark 7 Powder Check fix the powder-spray and probe-strike problems without replacing the sensor.
Deciding between our models? Start with Pro vs. Standard and RCM laser vs. Mark 7 PowderCheck. Fighting false alarms on the factory sensor? Read the troubleshooting guide.
